Dashboard view with custom METADATA

We got a great idea from @bdepaula of having a customizable way to track a set of experiments with the data we have of them (status, user, completed jobs, etc), and metadata set by the users in the configuration YML files like this:

METADATA:
    KEY1: value1
    KEY2: value2

Initially, this custom view can be set as a Table view that can select/add the columns to track. Then, we can include other ways to visualize this data as well.

This is feasible to do after the new GUI is finally released by extending the Home page. Also, we will need to extend the API to support these data requests.

Nevertheless, for some users, this will be quite useful in the short term. So, having it as a patch of the previous GUI is an alternative to handling it as a workaround. Also, we have the opportunity to handle it as a separate "supervisor" GUI project for people who will not need some features like authentication, specific views, and interactivity.
